How could Francis' apologists possibly spin doctor this scandal? Glad you asked?

It's really easy. They can say that either a) Francis didn't know Patricia was performing, because he left others to arrange it and besides, he doesn't know who she is anyway, b) Francis did know, but this is his way to get her to sing good music in hope of gently bringing about her full communion with his sect, c) Francis knows that Patricia has secretly done so already or d) pull a Michael Voris and ignore it until the scandal so it gets caught in that Memory Hole known as The Vortex, where truth and reality get trapped and ushered away to the darkness to avoid being exposed.
